青椒整枝技术的研究——环状剥皮对生育和产量的影响

Studies on Training Technique of Sweet Pepper

本文以“土佐狮子尖椒”品种为试材,对环状剥皮的作用进行探讨.经环状剥皮处理后,早期产量比对照增加29.4%～52.6%;果实的干物质占有率也比对照有所增加,而根系的发育情况和直径大于1毫米的粗根数目均低于对照.叶面积指数、净光合率及相对生长率在进行环状剥皮后也低于对照.

The Tosashishitougarashi was used as experimental material to probe into the action of girdling in this paper. The early yield in girdling plots increased by 29. 4%-52. 6% comparing with that in ungirdling plots, percentage of dry weight in fruit also increased in the girdling plots. The amount of root system and number of roots which are thicker than 1mm in diameter in girdling plots were less than that in control plots, The leaf area index, net assimilation rate and relative growth rate also decreased in the girdling plots.
